4th and 5th Grade Circuit Challenge
Ask your child to help you. Hint: Think about series and parallel circuits.
Part 1:
Phew! It was exhausting work, but you just hung all the Christmas lights on the tree at Rock Center. You are standing back admiring your handy work when all of a sudden the whole tree goes dark! You search through the tree and realize that a single bulb has cracked and broken. Your boss wants to replace every strand of lights. You don't think that it is necessary. Explain to your boss why just changing the broken bulb should restore light to the entire strand.
Part 2:
Okay, problem averted. You found the broken bulb and fixed the tree. How can this problem be avoided next year? Make a recommendation to your boss about a better system for lighting the tree.
